the west system is a room temp system and DOES NOT BENEFIT FROM POST CURE. THE TG is 129F and that be it, no improvement available.

You can raise the HDT via postcure (16 hours, ~120 F) to near 140 F per their engineering data. However, it's interesting that this doesn't appear to affect the Tg (onset values) per the info you received. Yikes.

Any materials science folks out there care to explain the relationship (or lack thereof) between HDT and Tg?
